REINFORCED-CONCRETE SHELTER.

Specification of Letters Patent.

Application filed May 22, 1913. Serial No. 769,213.

To all whom it may concern Be it known that I, HARRISON S. Tar'r, a citizen of the United States, and resident of Seattle, in the county of King and State of lVashington, have invented new and useful Improvements in Reinforced-Concrete Sheltors, of which the following is a specification.

My invention consists in an improved shelter particularly adapted to band stands and other out-of-door platforms.

In the drawings hereto annexed, which illustrate examples of my inventiom-Figure 1 is a vertical cross section of one form of shelter; Fig. 2 is a top plan view of the same from above with the roof thereof removed; Fig. 3 is a top plan view of the roof; Fig. 4: is a vertical cross section of a modified form of shelter; Fig. 5 is a detail showing the mode of arranging the reinforcing stays for the conical body of the shelter; and Fig. 6 is a vertical section 111 detail showing the mode of constructing strengthening webs for the shelter.

The chief characteristic member of my improved reinforced concrete shelter consists of the canopy structure marked A which I call the cone, although as shown in the drawings this member is, more strictly speaking, conoidal in form. This cone is provided with a support which, in the form shown in Fig. 1, is a central colui'nn devel oped from the apex portion A. of the cone and resting upon a suitable foundation B. The supports in the form shown in Fig. 4, are peripheral columns B upon which the outer and upper circumference of the cone A rests.

Referring to Fig. 1, the cone A developed downward from its apex portion A, as shown, to form a central supporting column, is a hollow shell of concrete reinforced by radial stay rods S which extend from a region at or near the point of support upward and radially outward to the edge A Circumferential stays S are wound spirally around and outside of the radial stays S and furnish tension resisting members to sustain the cone A. hen, as in Fig. 1, the central column or support is employed, the cone A is preferably left hollow to the base and communicates there with the drain pipe D, so that rain will drain inside the cone instead of falling over its upper edge.

When the canopy or shelter is of large Patented Aug. 4, 1914.

proportions, it should be further reinforced the axis of the cone and being composed of concrete reinforced by stays S which are anchored to the reinforcement S, S of the cone itself. In constructing a shelter with webs, the cone and webs will be cast together as one piece.

lVhile it is not absolutely necessarv, it

will be found preferable to provide a shelter with a roof which is constructed. preferably of reinforced concrete, the reinforcement consisting of the radial stays S and eircularly disposed stays 8*. In the form shown in Fig. l the roof It is laid in place over the webs and its dimensions are such that the periphery of the roof fits inside the upturned flange A which may form an integral part of the cone A. The roof R is apertured as by peripheral recesses R so that water will drain from the roof to the interior of the cone and pass out through the drain pipe Referring to Fig. 4, which shows a modification of the structure, here the cone A is supported by vertical columns B upon which the outer periphery of the cone A rests. The apex A of the cone terminates above the ground or floor F o that all portions of the floor may be occupied by persons using it. This will be found convenient if the shelter is used for a band stand. In this form of construction the roof R will extend over the outer edge of the cone A so as to provide protecting caves to exclude water from the interior of the cone. Even with this construction, however, it will be found advisable to provide a drain age outlet as at a at the apex A of the cone.

'By means of the construction above described, a shelter is provided which requires a minimum of bulk in its supports and which, by reason of its conical or conoidal shape, is peculiarly well adapted to out-ofdoor band stands, speaking platforms and the like, for the reason that the conformation of the cone enables it to serve as a reflector and diffuser of sound, whereas the flat or domed roof of such stands as usually constructed, act undesirably as reflectors and concentrators of sound.

I employ the terms cone or conoidal not in their strict geometrical sense, but as including canopy-like structures which may be circular or polygonal in horizontal cross section. These structures perform the functions of shelters or sound-reflecting bodies, or both.

What I claim and desire to secure by Letters Patent is:

A reinforced concrete shelter, comprising a canopy, a support therefor, said canopy bein an inverted cone, hollow, of concrete reinforced by stays radiating outward to the periphery of the cone, circumferential stays,
